PARALLEL FLIP-FLOP SETUP AND HOLD TIMING ANALYSIS - A computer aided design system determines the acceptable timing for a flip-flop cell. The system generates a search window having a pass edge and a fail edge and divides the search window into four sections using three quadsection values. For each of the quadsection values, the system simulates a timing analysis of the flip-flop and determines if each of the quadsection values pass or fail the analysis. The analysis may be done in parallel. If at least one of the quadsection values passes the analysis, the system causes one of the passed quadsection values to be a new pass edge for the search window. If at least one of the quadsection values fails the analysis, the system causes one of the failed quadsection values to be a new fail edge for the search window. If the search window is less than a predetermined window width, the system assigns the new pass edge as the determined timing. If the search window is not less than the predetermined window width, the system repeats the above, starting with dividing the new search window into four sections using three quadsection values.

Process for the Time Recovery of Sulphate of Potash (SOP) From Sulphate Rich Bittern - The present invention relates to a process for the recovery of sulphate of potash (SOP) from bittern. Kainite is obtained by fractional crystallization of the bittern. Kainite is converted into schoenite with simultaneous removal of NaCl and the filtrate (SEL) is used for production of KCl. Schoenite is reacted with aqueous KCl to yield SOP and the filtrate (KEL) is recycled in the kainite to schoenite conversion step. The production of KCl from SEL is carried out with the aid of dipicrylamine (DPA). Lime is treated with DPA in water for the production of highly soluble Ca (DPA)2, which in turn treated with SEL to produce insoluble K(DPA). K(DPA) is treated with HCl to produce KCl and insoluble DPA, which can be recycled for the production of Ca (DPA)2. The aqueous KCl thus obtained is treated with schoenite to prepare SOP. The KEL obtained along with SOP is recycled to generate schoenite.
